V-Ray | Procedural RUSTY METAL Shader | VRayBlendMtl, Procedural Masks, VRayDirt, AO & VRayBumpMtl

In this tutorial you will learn how to create a procedural Rust Effect that with the help of special masking techniques can be applied to any kind of geometry regardless of it's UV's. You can use this technique to quickly add procedural details to your assets. Like this you can texture a huge amount of assets very efficiently.
We will discover what are the advantages of procedural masks and why you should use them. I will then show you my preferred way how to create an easy to control render setup for a Rusty Metal Shader and walk you through each step. We will discover the basics of Ambient Occlusion or VRayDirt and how we can use VRayTriplanar Textures to procedurally project any kind of details on our assets.

I am using 3ds Max and V-Ray 5 in this demo but you can also use the same techniques for older versions such as V-Ray NEXT and V-Ray 3.
